Release VocalCoachBench for NeurIPS 2026 with canonical annotations and final leaderboard
e8e6bb6 verified | # VocalCoachBench evaluation snapshot | |
| This directory publishes the final 26 October 2026 results for **13 models** | |
| (9 open-weight, 4 closed API) and one no-audio majority reference. It accompanies | |
| [VocalCoachBench on Hugging Face](https://huggingface.co/datasets/Hayeonbang/VocalCoachBench), | |
| the [paper](https://arxiv.org/abs/2609.04241), accepted to NeurIPS 2026, and the | |
| [project demo](https://hayeonbang.github.io/VocalCoachBench). | |
| Dataset version: `canonical515_physical_audio_1064refs`. The released inventory | |
| has 515 recordings (A=207, B=308), 1,064 Top-3 expert references, 4,506 feedback | |
| blocks and 12,216 atomic claims (6,162 diagnosis, 4,593 correction, 1,461 strength). | |
| See [the public release notes](../metadata/PUBLIC_RELEASE.md) and the | |
| [canonical Top-3 policy](../metadata/CANONICAL_EVALUATION.md). | |
| ## Files and provenance | |
| - `leaderboard.json`: unrounded ratios, definitions, coverage, model caveats and | |
| hash-only source provenance. Metric values, coverage and notes match the | |
| verified final export; internal source paths were removed for this release. | |
| - `leaderboard.csv`: byte-exact copy of the final CSV; metric columns are | |
| percentages. Empty cells mean not evaluated, while `0` means an evaluated zero. | |
| - `provenance.json`: source snapshot/receipt hashes, public file hashes, the | |
| publication transformation, and hashes of the supporting released annotations. | |
| - `prompts/`: eight byte-exact generation prompt copies with file and | |
| whitespace-stripped runtime hashes in `prompts/manifest.json`. | |
| The internal receipt and experiment directories are not bundled. Their hashes | |
| record lineage; they do not make unavailable source files publicly reproducible. | |
| ## Metrics and denominators | |
| | Metric | Definition and population | | |
| |---|---| | |
| | Top-3 macro-F1 | Seven one-vs-rest classes over all 515 recordings and 1,064 references; average reference contributions within each recording. This is not F1@3 overlap. | | |
| | Segment macro-F1 | Seven-class macro-F1 on the fixed 262 evaluated segments, retaining invalid attempts. | | |
| | Segment Match | Predicted class matches any accepted reference for each of the 262 segments. | | |
| | Score ranking | Pairwise accuracy induced by quality scores; 189 triplets, 567 pair relations and 1,134 expert-reference attempts. Ties or missing scores fail. | | |
| | Direct ranking | Accuracy of audio A/B decisions against both expert orders on the same 1,134 attempts; malformed outputs fail. This is a separate task from Score ranking. | | |
| | Diagnosis strict hit | STRICT_HIT / 6,162 expert diagnosis claims. | | |
| | Diagnosis hit | (STRICT_HIT + COARSE_HIT) / 6,162. | | |
| | Prescription valid | VALID / 2,575 fixed slots (515 recordings × 5); missing prescriptions fail. This is not VALID / emitted prescriptions. | | |
| | Diagnosis-to-prescription E2E | Valid prescription linked to a supported model diagnosis / 2,575 fixed slots. It measures supported advice, not demonstrated improvement in singing. | | |
| No overall composite rank is defined. The majority reference has only a Top-3 | |
| score. Human expert-vs-expert Top-3 analysis has 513 eligible recordings, since | |
| two recordings have one expert; the leaderboard's model denominator remains 515. | |
| The 262-segment results use the fixed reference events released in | |
| [`annotations/segment_consensus_events.jsonl`](../annotations/segment_consensus_events.jsonl). | |
| Audio for 166 clips is packaged; the other 96 clips must be resolved from their | |
| source datasets. Use these exact events rather than selecting arbitrary rows or | |
| rebuilding a different consensus population. Frozen internal runtime manifests, | |
| model inference runners and judge runners are not bundled; the released events | |
| and available audio alone do not constitute a complete reproduction pipeline. | |
| ## Evaluation and model policies | |
| Primary structured results use `strict_all_attempts`: malformed, missing and | |
| backend-error outputs remain failures. Stored first responses are retained rather | |
| than replaced with successful retries. Top-3 references have equal total weight | |
| per recording. The seven public labels are PITCH, RHYTHM, DICTION, BREATH, | |
| PHONATION, TECHNIQUE and EXPRESSION; historical `VOCALIZATION` maps to PHONATION. | |
| Dataset-B annotation joins use physical-audio SHA-256, not filenames. | |
| Claims results use the corrected515 **format-reported** extension: invalid Claims | |
| JSON emits no claims, and all fixed denominators remain. This differs from the | |
| older schema-penalized policy in historical protocol documents. The judge is | |
| `openai/gpt-oss-120b`; unresolved judge errors are zero in the verified cohorts. | |
| Main uses structured JSON prompts for FunAudioChat, Kimi-Audio, MiMo-Audio, | |
| Qwen2.5-Omni, Qwen3-Omni, R1-AQA, GPT-Audio 1.5, Gemini 3 Flash Preview, | |
| Qwen3.5-Omni Flash and Qwen3.5-Omni Plus. Simple uses separate short Top-3, | |
| score, segment and overall-feedback prompts for Audio Flamingo 3, Music Flamingo | |
| and Covo-Audio, with their original text-extraction route. Simple overall feedback | |
| is decomposed into claims before judging; it is not the separate Natural task. | |
| The prompt manifest identifies the appropriate files; Main prompts must not be | |
| substituted for Simple. | |
| Audio Flamingo 3 and Music Flamingo Direct use A audio, one second of silence, | |
| then B audio in one WAV with interval instructions. Their dynamic Direct wrappers | |
| are not included; the bundled Main Direct prompt expects separate labeled inputs. | |
| Covo-Audio Direct is N/A, and its 515 Claims outputs produced no usable claims. | |
| FunAudioChat Direct retains 18 failed first responses (549/567 parsed decisions). | |
| GPT-Audio 1.5 Direct uses the October 14 strict-first cohort; its other tasks reuse | |
| audited historical responses. Closed API snapshot/runtime equivalence and | |
| transport retries before each stored raw row are not established. | |
| The prompt copies preserve frozen protocol text, including trailing whitespace. | |
| Their inclusion does not supply model adapters, system prompts, runtime wrappers, | |
| claim extraction/judge prompts, predictions or a complete reproducible inference | |
| and judging kit. Historical v5 examples on the demo are illustrations from a | |
| separate cohort; use this snapshot for the current aggregate results. | |
